Either one or the other.......

I contacted Big Gun about their Over Rev CDI, They talked to the people who manufacture the product and they said the CDI advances the timing between 2% and 4% ( I am not sure how much that is) depending on the machine. My question is which one should I keep? I have them both installed and when I try to start it, it drags like it has a low battery and when it does start and I run it I feel no difference in power like I am supposed to. I had the CDI on already and then installed the sparks.

'I have them both installed'

id keep the cdi if its advancing the timing and reving higher

Yeah the CDI doesn't have a set RPM, It lets the engine go to its limits. I do need to figure out how to convert the timing into % so I can figure out what my range is.

well if its 360° for a rotation and its 2-4% wouldnt that be 7.2 - 14.4? cant be right. IDK usually the CDI boxes advance it about 1-2 degrees max unless its adjustable.

EDIT: Just thought about it after I posted. It wouldnt be 360° before or after TDC I think its to 180° before or 180° after. So that would make it 3.6 - 7.2?

Thanks FlewByU352, I am going to take the sparks out tomorrow.
